The agency claims it has pulled off a major turnaround by hiring hundreds more staff and reorganizing how they work to bring new levels of efficiency to air travel.

It’s claimed the time it takes to go through security checks at major airports has been drastically slashed from hours in some places to just minutes.

The biggest improvement is at the worst airport — Chicago O'Hare — where lines that were once 2 hours long are now down to just 9 minutes, according to TSA. The news comes to the relief of many travelers as the Lollapalooza music festival will overtake the city for four days at the end of the month.
